Not really. We had thermostats and mechanical timers not even 20 years ago in washing machines and dryers. No computers necessary. Arguably most work has been government regulation, or cost of resources like gas, electric, and water, in the name of efficiency. Those components were made for decades, worked for decades, and were available decades later. Now machines are deprecated 1-2 years after purchase and parts are unavailable, and un-repariable because of potting and proprietary chips and tamper resistant roms.

Ok we seem to live in different universes. Where I live washingmachines are repairable, it is my decision if I buy ultra high tech phones where everything is soldered together or go for fairphone or framework laptop. But yes in general things are less repaired in the rich countries. Mostly becauce time is far more expensive, so replacement is cheaper. But in general there is a clear tendency to more regulation for thejright to repair, endurability and so on. Check out the security update span of newer phones. They get longer support than before 5 years. I know it can be far better. But it is also just not true, that everything is consistantly getting worse.
